METHOD OF FORMING THREAD TIPS.

Application filed June 23, 1923.

7 new and useful Improvements in Methods of Forming Thread Tips, of which the following is a specification.

This invention relates to improvements in the method of manufacturing silk, cotton or linen thread used for stringing beads and the like, and more especially to the preparation of the end or ends of the threads so that the same will easily pass through the openings through the beads, thereby doing away with necessity of using a needle.

An object of the invention is to provide a suitable silk, cotton or linen thread, which will preferably be formed from three separate cords which will be twisted together and cut into the desired length according to the length that the string of beads is to be, and then treat the ends thereof with amaterial which will harden the same, so that they will freely and easily pass through the openings in the beads.

A further object of the invention is to provide a suitable thread of silk, cotton or linen, which may be made from one or more threads, and which will have its ends dipped in a bath of hot bone glue, after which in a light solution of bees wax, which will make the same sufliciently stiff for easily passing through the openings in the beads to be strung, though not so stiff that the ends will split or crack.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application Figure 1 is a side elevation of a thread used for threading beads, showing one end of the same prepared in accordance with my improved method;

Figure 2 is a front elevation of the imprplved tip portion as coated with bone glue, an

Figure 3 is a front elevation of the tip completed with a coating of bone glue, and also a coating of bees wax.

Serial No. 647,348.

Like characters of reference are used throughout the several views and the ac companying drawings to designate corresponding parts.

In carrying out my invention, I employ a thread. 1 made from silk, cotton or linen, which may be composed of one or more cords as indicated by 2.

These cords 2 are spun and twisted together, and are cut the desired length, according to the length of the string of beads, after which the ends 3 are immersed in a bath of hot bone glue, which will tend to harden the said ends to a certain degree, so that they can be used in the manner of a needle for threading the beads 4 on the thread. The ends 3 will then be quite still, but will be somewhat pliable so that the same will not readily crack or split.

After the hardening process has been applied to the ends 3 of the string 1, they will be immersed in a light solution of bees wax, which when the ends of the thread are passed through the openings in the beads, will tend to fill the crevices on the edges of the beads, thereby doing away to a great extent with the usual chafing or cutting of the string by the beads. It will therefore be apparent that the life of the string will be very much longer than the ordinary string used for this purpose.

The old method of stringing beads is to take a fine needle and threading the same with a fine thread so that the needle and thread may be passed through the openings in the beads. This method is obviously inefficient, since a small thread only can be used, while in my improved method, the maximum size of thread may be utilized thereby providing for the greatest possible life and eficiency of the thread.

Many minor changes may be resorted to without departure from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. The method of forming a tip on a. thread for use in stringing beads, consisting of immersing the ends of the thread in hot 5 thread for use in stringing beads, consisting in twisting one or more cords of silk, cotton 7 or linen together, cutting the same in the desired length; immersing the ends thereof in a solution'ofrhot bone glue; and finally immersing the said encls'in a light solution 1 of bees Wax.

In testimony whereof aifix my signature.
